Title:
Random Graphs

This is a Short Lecture Series in Mathematics (SLSM) consisting of 4 lectures of 90 minutes each. This is the first lecture in this series.

Abstract: The first half of the mini course will be an introducing to the two classical models of random graphs (a.k.a. Erdős-Rényi random graphs) and discuss the phenomenon of phase transition. We will also discuss thresholds for monotonic properties with examples including connectivity threshold and sub-graph containment threshold.

In the second half of the course we will consider other kind of random graphs. In particular, we will discuss various models for complex networks, including Albert-Barabási preferential attachment models. We will discuss "scale-freeness", asymptotic degree distribution and "small-world phenomenon". Properties of super and sub-linear preferential attachment models and some recent developments in de-preferential attachment models will also be discussed.

If time permits we will also introduce the random geometric graphs and discuss asymptotic of the connectivity threshold.

Title:
Weyl algebra, Hyperbolic space and Noncommutative Hyperbolic plane

We propose a Weyl system represented on the Hilbert space $L^{2}(\mathbb{H}^{2}, d\mu)$ where $\mathbb{H}^{2}$ is the Hyperbolic plane and $d\mu$ is the corresponding hyperbolic measure. We give four canonical derivations on the algebra and using them propose a Lindbladian which would enable us to study geometric properties of the Weyl algebra.
